rTwit adds a short code that allows you to embed any Twitter feed into posts and pages on your WordPress site.
This plugin came about from my need to embed tweet from software authors on a page describing the software.
Requests are cached for 30 minutes, by default, so that subsequent page views can load from cache rather than having to reload and reparse the Twitter feed. Links are set to open in a new window, although that is optional.

Simple Social Icons is an easy to use, customizable way to display icons that link visitors to your various social profiles. With it, you can easily choose which profiles to link to, customize the color and size of your icons, as well as align them to the left, center, or right, all from the widget form (no settings page necessary!).
*Note: The simple_social_default_glyphs filter has been deprecated from this plugin.
